qwerty

There are very few things that are surrounded with as much hearsay and rumor as the origins of the QWERTY layout of typewriters and keyboards. The reason behind the QWERTY layout isn’t as simple as ‘so the bars for each letter don’t collide with each other.’ That’s nonsense – it would make far more sense to improve the mechanism before changing the arrangement of the keyboard around.

That’s not the only fallacious argument for the creation of QWERTY. It’s also been called a marketing ploy; Stephen Jay Gould popularized the idea of the QWERTY keyboard being as it is so a salesman could peck out TYPE WRITER on the top row [1]. This also makes little sense. Why would the top row and not the home row be so privileged as to contain all the letters the make up the name of the machine. For that matter, wouldn’t a sales pitch be more impressive if TYPE WRITER were typed with one hand?

This doesn’t mean there’s not a method behind the madness of QWERTY – it’s just not as simple as jammed typewriter mechanisms or appeasing the wishes of salesmen in the 1870s. QWERTY didn’t come out of thin air, though, but folk tale history of this keyboard layout is sadly deficient.

Back in the day, we had smartphones with physical buttons. Not just power, volume, and maybe another button on the front. Whole, slide-out QWERTY keyboards right on the underside of the phone. It was a lawless wasteland, but for those who yearn for the wild-west days of the late 2000s, [Liviu] has recreated the shortcut buttons that used to exist on the tops of these keyboards for modern-day smartphones.

There were lots of phones that had shortcut keys on their keyboards, but [Liviu] enjoyed using the ones that allowed him to switch between applications (or “apps” as the kids are saying these days) such as the calendar, the browser, or the mail client. To recreate this, he went with a few NFC tags. These devices are easily programmed via a number of apps from your app store of choice, and can be placed essentially anywhere. In order to make them visible to the phone at any time, though, he placed the tags inside a clear plastic case for his phone and can now use them anytime.

If you’ve never used or programmed an NFC tag, this would be a great project to get yourself acquainted with how they operate. Plus, you could easily upgrade this project to allow the tags to do any number of other things. You can take projects like this as far as you want.

[BiOzZ] wanted to try a different keyboard layout than the ubiquitous Qwerty, so he grabbed an old keyboard and converted it to the Dvorak setup. This was accomplished by first popping off all of the keys from the black keyboard seen above, and boy did he find a mess underneath. It was nothing that a trip through the dishwasher (for the case only) wouldn’t fix, and the next step was to replace the keys in a different order. He found that a couple of them wouldn’t just go back in a different place, but had to be rotated 90 degrees to fit. Not a huge problem, you can see that he overcame the visual speedbump of letters facing the wrong way by adding his own letter labels. From there he walks us through the process of getting Windows to switch to the Dvorak layout.

I went through a similar process at the end of last year. I was experiencing a lot of pain in my hands from my prolific feature writing here at Hackaday so I chose to try out the Colemak keyboard. The white keyboard above is the one I repurposed using that layout. I found it quite easy to switch between two keyboard layouts using Ubuntu. After you’ve set it up in the keyboards dialog a layout icon appears on the panel. It wasn’t hard to pick the new key locations up, but it did reduce my typing speed by a factor of 8. In the end I found that adjusting my chair height and keeping my hands warm did the trick and I’m back on the Qwerty where I belong.

Microsoft is showing off five concepts for added mouse functionality. All of them seek to replace traditional move-and-click with touch sensitivity through either capacitive sensing, video recognition, sensor articulation, or laser scanning. We’re excited about the prospects of some of these features but at the same time wonder what this does to the price of this much-abused peripheral. After the break we’ll touch on each of the devices, along with time references for the video embedded above. Continue reading “Five concept mice add multi-touch control”→

[skeezix] has got his hands on one of the first Pandora dev kits to make it out the door and took a few photos. This is 1 of the 20 MK2 devboards that were produced. Although, not final it certainly is close to the version they’ll be shipping. Pandora is a Linux based portable game console. The main chip in the clamshell device is a TI OMAP3530. It has OpenGL hardware acceleration and an 800×480 touchscreen. A QWERTY keyboard is included along with analog and digital game controls. WiFi, bluetooth, USB host, TV-out, and dual SDHC card slots round out the package. The team has already presold 4000 devices.

[morcheeba], who you should remember from CVS camera hacking, picked up a Peek and took some pictures while tearing it down. The Peek is a $100 QWERTY device with a simple OS designed only to check email. The device is being sold by T-Mobile with a $19.95/mo data plan. There’s nothing too spectacular to see other than 16MB of flash memory and a TI OMAP processor.
